SOLD my 2014 36FK

We loved the Seneca but did not enjoy the small master and poor TV viewing positions. Now that we have some experience we are looking for a late model (2019) 37HJ. I have a couple questions about ttt he e newer models I cannot find answers for. 1. Does the 2019 M2 have one filler? Iím looking at pictures and donít see a filler neck on the passenger side. Is the leveling Jack system in the 2019 still a BigFoot system?

Any inputs on the later model HJ is appreciated.

We have a 2018.5 HJ.
2018.5 and newer are on the S2RV chassis, not the M2. The S2 has one tank of 100 gallons with one filler on the driver side. Unfortunately the DEF is at the drivers door and the diesel is about 25 feet back. You can not fill both in a single transaction. The shower on the HJ is pretty small, in fact, it is smaller than the shower we had in our 2006 Seneca.
The good thing is there is a whole lot of information here on the forums for fixes and modification.
I have documented a whole lot of work on our on our YouTube channel.
Good luck.

The easiest way to tell the M2 and S2 chassis is the fuel fill locations, the M2 has the tank under the cab on each side and the S2 has the filler above and to the rear of the drivers rear tire. There are many advantages to the S2 and is my preference. Be aware on 2018 models, many don’t know about the chassis change mid year and advertise as a 2018 when it is actually a 2018.5. The change in chassis at 2018.5 also had some floor plan changes like in the RB, in 2018.5 they did a front tv layout like the HJ has. The 2018.5 and up use the Equalizer leveling system.

We always liked the HJ but the only issue I had with it was the waste tank sizes but that’s an issue that depends on how you intend to use it. We ended up buying a 2018.5 (S2) RB as we boondock a lot and the bath and a half models have much larger capacity of black and grey tanks.

Someone taught me an easier way while in Moab last year:
They said the easiest way was to check to see if it has the DEF bypass hacked into the emissions system.

I thought it was somewhat sarcastic at the time, but they said everyone should look to see if it has the original DEF header connection attached to the factory wiring harness.

Not sure why that would show if it was an M2 or S2, they both have a def tank and header. What do they mean by def bypass hacked in?

The fuel filler is much easier than removing panels to check the def system.
